STORAGE OIL-TANK.

SPECIFICATION forming part of Letters Patent No. 234,678, dated November 23, 1880.

Application filed September 27, 1880.

To all whom it may concern:

Be it known that I, CHARLES KENNEDY, of Fredericksburg, Virginia, have. invented a new and improved construction and arrangement of storage oil-tanks to prevent the possibility of ignition of the oil contained therein by reason of the vapors and gas being brought in contact with lightning, of which the following is a specification.

The object of the invention is, first, to take out of the tank and to convey away from the same to a proper distance the Vapors and gas that arise from and are generated by the oil; secondly, to prevent the escape of vapors and of gas from the pipes used for filling and emptying the tank during the process of filling and of discharging the same.

Thenneans for the accomplishment of these purposes is illustrated by the annexed drawing, in which A represents the tank and B B the closed roof or dome of the same, both be ing made of sheets of iron riveted together in the ordinary manner.

The iron pipe 0, being of proper size, is inserted through the center of flooring of tank A, and is carried vertically through middle or tank A until it reaches a proper position in the center of dome B B. The pipe 0 has immediate outlet from tank Ainto the ground at e,

and is extended under ground, as indicated at ff, a suitable distance from tank A, in order to safely carry 0d the vapors and gas without a possibility of their escape until they reach the end of pipe 0. The pipe 0 is secured in position by a collar, E, and the support which it receives from its subterranean position, as described, and from the pressure of the liquid contents of tank A.

(No model.)

For the purpose of filling tank the pipe F is inserted through flooring of tank A and is carried Vertically toward the root or dome B B a proper distance, as indicated at its mouth G. The pipe F has immediate outlet from tank A into the ground at g, and is extended under ground any desired distance in order to prevent the escape of vapors and of gas that may arise from the same during the passage of oil into tank A.

In order to discharge oil 'from tank A, the pipe H is inserted through flooring or bottom of tank A in same manner as described in connection with pipe 0 and pipe F, andis carried under ground, as indicated at h, and is extended any desired distance under ground in order to prevent escape of vapors and of gas until they reach the mouth of the same.

Having thus described my invention, what i claim as new, and desire to secure by Letters Patent, is-

The combination of a tank, the motor dome B B, constituting an interior chamber for the reception of the gases and vapors that are generated by and arise from the oil, the pipe 0, extending from said chamber through the body of the tank, thence wholly under ground to a distance from the tank, for the continuous reception of the vapors and gases and for the conveyance of the same out of the tank as they are generated from the toil, and of the inletpipe F, opening into said chamber from under ground, and the-undergrounddischargepipe H, substantially as set forth.
